ToiZZ whom it may concern: ,V y

Be it known that I, CLIFFORD I. Hiirr, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful improvements in Eg -Beaters; and I dohereby declare that the ollowing is a full, clear, and exact descriptionof the invention, which will enable others skilled in the .art to whichit appertains to make and use the same.

This invention has reference to certain new and useful im roveinents inmachines for beating eggs w ipping cream, and for various other ansimilar urposes.

One of the objects of t e presentimention is to construct a machine ofthe character herein referred to which 'shall be operated by power; thatis to say the irlachine includes beaters or whippers which are suitablygeared to a power s aft and said shaft is adapted to have clutchedthereto power means, preferably a flexible shaft for operating the saidbeaters or whippers, instead of by hand, which has been the usualpractice.

A further object of the invention is an egg beater or cream whipperprovided with beating elements which are constructed so as -to outthrough the material instead of cilrryin the material, said beatingelements suitacbly geared together, which said gearing is inclosedwithin a housing or casing and adapted tobe clutched to suitable powermechanism; the housing or casing provided with handeholds or grippingmeans for steadying the machine during the operation of the beatingelements.

With these and such other ends in view as ap` ertains tothe nature andscope of the inven ion the latter consists, essentially, of the novelfeatures, details of construction, and combinations of parts whichhereinafter will be more fully described, illustrated and claimed.

ln the drawings forming a pai-t of this application-Figure l. is a sideelevation of myimproved inach ine, showing a flexible shaft coupledthereto; Fig. i? is a vertical section of the saine, oinittiiixlr thebeating elements; Fig. 3 is an enlarged cross-section on the line 3-8 ofFig. l; Fig. a is a detail in perspective showing the clutch connectionbetween the power shaft and flexible shaft, and Fig. 5 is a modificationof the gearing connecting the shafts carrying the beating elements, withthe drive shaft.

Like numerals of reference indicate corres ondiiig parts throughout thefigures.

n the drawi s, 1 designates a head and said head is rovided with a pairof depending tubular earings 2, which are suitably spaced apart, inwhich are journaled shafts 3, of considerable length; said shafts attlieir lower ends being unattached and without a bearing in anysupplemental frame part, and for a portion of their length are squared,as at 4. At the juncture of the squared portion 4.- of the shaft, withthe round portion 3, thereof, a head 5 is secured and to said head,diametrically opposite each other. the ends 6, of beating elements 7 aresecured, by being soldered, or otherwise attached, and said beatingelements which have preferably a wave formation, where they intersectwith the shaft, are soldered or otherwise suitably attached.

By squaring the lower ends of the shafts and omitting the usual bearingfor the extreme ends of the shaft, I rovide an eilicient beater for eggsas well) as an eiiicieiit whipper for cream. It has been dem onstiatedthat that portion of the shaft to which are attached the beatingelements should be squared so that the shaft will cut its Wa. throughthe material, the same as the beating elements, and not carry thematerial with it and also that the ends of the shafts should be yleft asfree as possible, omitting the usual supplemental frame and hub, whichpicks up the material and lessons the efficiency of the machine.

To the upper ends of the shafts 3 are secured bevel gears 8 and saidgears are in mesh with bevel pinions 9 carried on a power shaft 10. Thepinions 9 are preferably arrauged backto back for the purpose ofdriving` the gears 8 and shafts 3 in 'opposite directions. The beatingelements? or. the lower ends of the shafts are normally disposedtransversely to each other, as shown in Fig. l.

The shaft l0 has a bearing in a cap-plate l1, which is 0f considerablelength, and which has a hand-hold 12 ahime end and a long bearingportion 13 at its opposite end,

which may also be used as a hand-hold or gripping portion. Saidcap-plate 11 has the gear shaped portions 14 to receive the pinions 9and also provided with portions 15 to inclose the gears 8 in the head 1.The head and cap-plate are preferably secured at points 16 and 17,whereby the cap-plate may be removed, and with it the shaft 10 andpinions 9 and enables the operator to get to the gears 8, either forremoving the same from the shafts 3. so that said shafts may be takenfrom thc bearings, or for any other reason.

On the outer end of the shaft 10 is carried `a clutch-member 18 which isformed with a recess or slot 19 through which the shaft 10 projects. 0nthe outside of the long bearing portion 13 of the cap-plate and removedinwardly from the end thereof a suitable distance, is attached aspring-locking-plate 20 which is suitably arranged to detachably hold asleeve 21 on the bearing portion 13 of the cap-plate. T he sleeve 20 hasan annular groove 22 which slips under the spring-locking-plate 20, whensaid sleeve is passed onto or over the said bearing portion 13. Thissleeve has suitable connection with the casing 23 of a tiexible shaft 24and is the means by which said'liexible shaft may be readily and easilyconnected with the machine. To connect the flexible shaft'proper withthe drive shaft 10, when the sleeve has been slipped into place on thebearing portion 13, or asthe same is being slipped into place, the endof the shaft 24 is provided with a clutch-head Q5 having a recess 26.When the clutchmember 18 and clutch-headfl are united, the head isinserted into the recess or slot 19 in the member 18, and the shaft 10projecting through the member 18 is seated in and has a bearing in thehead 25. It is obvious that the head 24 should be the same shape as therecess or slot in the member.

ln Fig. 5 the shafts 3 are provided with intermeshing spur-gears 27, andone of said shafts 3 carries a bevel gear 28 in mesh with a bevel pinion29 on the shaft 10. This construction is more adapted for a smallermachine than is shown in Fig. 1 and intended to run much slower. ln allother respects it will be of thel same general construction, as-

seen in Fig. 1.

The foregoing machine has been designed more particularly for use inbakeries and similar places. where a simple, durable and eiicientmachine is needed and where a high speed machine is necessary.

Having thus fully described my invention,

what ll claim and desire to secure by Letters Patent of the UnitedStates, is

1. An eg beater comprising in combination, a han le provided with aplurality of recesses, a driving shaft extending longitudinally throughsaid handle and projecting from one extremity thereof, a plurality ofoppositely disposed gears carried by the shaft and mounted in therecesses .in the handle, a plurality of beater shafts, a gear carried bythe upper extremity of each beater shaft and mounted in the recesses inthe handle, each of said gears meshing with one of the oppositelydisposed gears carried by the driving shaft, a cap plate for inclosingthe gears within the recesses in the handle, a bearing surrounding eachof the beater shafts, said bearings being integral with, and dependingfrom the cap plate, and means for connecting the driving shaft with asuitable source of power.

2. An egg beater comprising a handle, a drivin shaft extendinglongitudinally therethrong a plurality of oppositely disposed gearsmounted on said shaft, a plurality of beater shafts, a gear on the upperextremity of each of said beater shafts and meshing with one of theoppositely disposed gears, a cap plate carried by the handle forincasing the gears, a bearing sleeve integral with,

and depending from said cap plate and sur; rounding each of said beatershafts, and means for connecting the driving shaft with a suitablesource of power. Y

3. ln a device of the character described and in combination, a handlemember bored for a portion of its length to provide bearings for theshaft, and having enlarged recessed portions, a shaft journaled thereinand adapted to be connected to a suitable source of power, said shafthaving a pair of oppositely disposed bevel gears mounted in one of saidrecessed portions, a pair of vertically extending shafts, having bevelgears on the upper ends thereof, one being in mesh with one of saidfirst Ymentioned gears, said second mentioned bevel gear beingpositioned in the other of said recesses in the handle, a plate memberfor the handle having depending bearing members for said verticalshafts.
